What to Focus On
- Variations are differences among closely related organisms.
- Heredity is the passing of traits from parents to offspring.
- Genes control the expression of traits.
- Mendel began his work in 1857.
- He studied 10,000 pea plants of 34 varieties.
- Pea plants had clear, contrasting characters.
- Monohybrid cross studies one trait at a time.
- F1 shows the dominant trait.
- F2 shows a 3:1 phenotypic ratio.
Common Mistakes to Avoid
If a trait is visible in the first generation, it must be the stronger or more common trait in the parents.
Phenotype and genotype mean the same thing.
If one parent passes a dominant factor, the other parent’s factor is useless.
